LPL Financial is forecasting that for 2015, stocks will be up for the seventh year in a row at a 5- to 9-percent clip, with bonds flat.

However, the 12 months may not be steady as she goes. “After several years of below-average swings in equity prices, 2015 could be a bumpier year for investors,” the financial giant warned Tuesday in its annual outlook.

That being said, the company cautioned investors to stay the course and not overreact to the natural downdrafts.

For 2015, LPL predicted the U.S. economy will grow at 3 percent (the average for the past half century), inflation will be modestly higher, and the earliest the Federal Reserve will raise interest rates will be late in the year.

On fixed income, LPL said high-yield bonds and bank loans will continue to stand out because of good corporate fundamentals and low defaults.
